Whims could be so much more, and it's very disappointing that they haven't been fixing or making new ones.
The Sims in the Sims 4 are basically shallow husks, without any discernible personality. Any personality you have to use your imagination to create.
Yes, they have traits, but they still have little effect on them. And they do have Aspirations, but the majority of aspirations have no effect on their personalities at all. And we still don't have Wants, Fears, Interests, or an Attraction system.
The least they could do is fix the broken Whims and make them useful again. Sadly, they don't seem to be bothered.
This game is basically only for building and creating pretty sims. All shallow, no gameplay in sight.
